VICTOR E. KENT, F JOHNSON CITY, TENNESSEE, ASSIGNOR OF ONE-THIRD TOJAMES A. MARTIN AND ONE-THIRD TO RICHARD F. BREWER, BOTH OF JOHNSONCITY,

TENNESSEE.

Johnson City, in the county of \Vashington I and State of Tennessee,have invented certam new and useful Improvements 1n Cattle-Guards, ofwhich the followingis a specification.

This invention relates to cattle guards and designed more partlcularlyas an improvement on the cattle guard disclosed in my 00- pendingapplication filed January 9, 1912, Serial No. 6703M.

T he guard disclosed in the said application embodies fixed guardmembers which aresuspended for swinging movement and it is one aim ofthe present invention to simplify and improve the construction of thefixed guard sections and provide an improved means for suspending themovable sections.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which I Figure 1 is atop plan view of one form of the improved guard. Fig. 2 is a verticalsectional view therethrough. vertical transverse section on the line 3-3of Fig. 2. Fig. 4C is a detail view in elevation of a portion of one ofthe fixed guard. 5 18 a View similar to Fig.2.

sections. Fig. illustrating a slight modification of the invention.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingby the same reference characters.

In the drawings, the rails are indicated by the numeral 1 and the tiesupon which they are mounted by thenunieral 2.

As before stated, the invention contemplates the provision of fixed andmovable guard sections, and in that form of the invention shown in thefirst four figures of the drawings each of the fixed sections consistsof a pair of plates, each indicated by the numeral 3 and these platesare of greater or less length, depending upon whether they are to extendbetween the rails 1 or are to be located outwardly of the said rails, asclearly shown in Fig. 1 of the drawings. As illustrated in Fig. 2 of thedrawings, the upper edges of the ties 2 are cut away as at 4: betweenand beyond the rails 1 and Fig. 3 is av i l l l l l i l l Specificationof Letters Patent. Patgnfied June 30 1914,

Application filed May 28, 1912.

Serial No. 700,263.

the plates 3 comprising each guard section are disposed against the cutaway surfaces 4 1n the relation shown in the said section 2 and aresecured in place by means of spikes 5 driven therethrough and into thesaid ties. Each of the plates is formed at its upper edge with anupstanding flange 6 and these flanges abut against eachother as shown inthe drawing and at intervals are secured by means of rivets or othersuitable fastening devices 7. Each of the flanges 6 is toothed asindicated at 8 and the teeth of the two flanges of each fixed guard arealternated so that a continuous saw-tooth edge is presented at the ridgeof the section as illustrated in Fig. 3.

In the form of the invention shown in the first four figures of thedrawings,each movableguard section of the device includes a tread-plate9 which is of metal and has its forward and rear edges flanged as at 10and this plate is provided with a number of upstanding spikes or spurs11 which are arranged relatively close together, as shoWn in Fig. 1 ofthe drawings, it being understood that these spikes or spurs extendthroughout the entire area of the upper sur face of the plate. Theseplates 9 are sus pended between the ties 2 from bars which extendparallel to the rails andoutwardly of the same. Each of these bars isinclicated at 12 and the flanges 6 of each fixed guard section areformed with registering notches 13 in which the bars 12 are engaged.

It will be understood by referring to Figs. 1 and 2 of the drawings thateach bar has its end portions bent to extend downwardly as at 14 andtwisted to form flat terminal portions 15 which are disposed against theupper face of one of the plates 3 of each endmost fixed guard section,and these terminal portions of the bars are secured by spikes 5 as shownin Fig. 2 of the drawings.

In suspending the plates 9 from the bars 12,

a pair of clevises 16 are pivotally supported as at 17 between each twoof the ties 2 and a link 18 is connected to each clevis 16 and by meansof a link 19 to an eye 20 secured upon the upper side of the plate 9.This arrangement is clearly shown in Figs. 2 and 3 of the drawings andit will be understood that the tread-plates 9 are free to swingforwardly and rearwardly and also laterally.

It will be observed from inspection of iFigs. 2 and 3 that the plates 9are supported in a horizontal plane substantially (to-incident with thelower edges of the acljaccnt ones of the plates 3 of the fixed guardsections and that the flange 2 and rear edges of the said plates 9 arelocated adjacent to the lower edges f the plates 3.

In the form of the invent-ion shown in Fig. of the drawings, triangularblocks 21 are substituted for the plates 3 comprising theh'xed guardsections of the device and spilres are driven through the pieces ofblocks and project at their upper ends above the apex or ridge of eachblock and serve the same purpose as do the toothed flanges (5 ot' thesaid plates 3. Each block 21 in this form of the invention is formedwith a notch 23 corresponding to the notches 13, previously described,and receiving the supporting bar 24 for the movable or suspendedguard-sections. The ends 01"? the bar 24 in this form of the inventionare bent and secured in the same manner as previously described.

In this form of the invention the movable or suspended guard-sectionconsists of two boards, one off which is indicated by the numeral 25 andthe other by the numeral 26, and pins 27 are driven through the board 26and the board 25 is disposed against the under side of the board 26 andthe eye-members of the suspension which corresponds to the eye 20,heretofore described, are provided with shanks 28 which are securedthrough the two boards and hold them in assembled relation in the mannershown in Fig. 5.

Having thus described the invention what is claimed as new is 1. In acattle guard, spaced guard sections, each including a body havingoppositely inclined surfaces the bodies of the sec tions at their ridgesbeing formed with notches, and a bar extending through the notches andsecured at its ends to the outer sides of the endmost sections.

In a. cattle guard, spaced. guard sections, each including a body havingoppositely inclined surfaces, the bodies of the sections at their ridgesbeing formed with notches, a bar extending through the notches andsecured at its ends to the endmost sections, and other guard sectionssuspended for swinging movement between the first mentioned guardsections.

itions, each including from the said bar,

3. In a cattle guard, spaced guard secplates arranged in oppositelyinclined relation and provided at their upper edges with upstandingflanges, each of the flanges being formed at intervals with teethextending less than the oiltire height of the flange, the plates beingarranged-with theteeth of the flanges alternating, means securing theflanges together, the flanges of the plates of each sectionbeing formedwith notches, a bar seated within the notches, and a swinging guardsection supported from the bar andextending between the first mentionedguard sect-ions.

4, In a cattle guard, spaced guard sections, each including platesarranged in oppositely inclined relation and provided at their upperedges with an upstanding flange, each of the flanges beingformedatintervals with teeth extending less than the height of the flange, theplates being arranged with their flanges abutting and with the teeth ofthe flanges alternating, securing elements fitted through the flanges,the flanges of the plates of each "section being formed with registeringnotches, the said notches extendingthe entire height of the flanges, abar titted within the notches, the bar having a down-turned endextending beside the up-- per face of one of the inclined plates andprovided with an opening, the plate being provided with an opening withwhich the opening in the down-turned end of the bar is in registration,a securing clement fitted through the said opening and designed tobedriven into a tie straddled by the plates, and a movable guard sectionsupported by the said bar bet-ween the first mentioned guard: sections.1

5. In avcattle guard, spaced guard sections, said sections havingoppositely inclined surfaces and each section being provided at itsridge with a notch, a bar re movably disposed edgewise within thenotches, means securing the ends of the bar to the end ones of the guardsections, and a movable guard section suspended from the bar between apair of fixed guard sections.

In testimony whereof I aflix my signature in presence of two witnesses,
